EEM4: Development of Tools for Probabilistic Uncertainty Analysis in Environmental Risk Assessment of Chemicals

Description

The risk to wildlife or the environment posed by a given chemical depends on whether its environmental concentration is greater than set quality objectives (the risk quotient). Both environmental concentrations and quality objectives are calculated based on chance (probability), a method that is not reliable. A chemical’s likely effects can best be assessed using the sensitivity of wildlife seen in tests on each species (ecotoxicology.) This project aims to develop computer software to integrate data from various sources, making probabilistic uncertainty analysis available to beginners as well as experts in environmental risk assessment. Ways to deal with the uncertainties of the risk of chemicals will be applied to current technical and managerial procedures used to evaluate chemicals in the EU.
